Análisis de las correlaciones entre el CBR, DCP, propiedades índice y mecánicas en suelos de las parroquias Guaytacama y Toacaso del cantón Latacunga, provincia de Cotopaxi

Abstract

The purpose of this experimental research work is to analyze the types of soils existing in the Guaytacama and Toacaso parishes, starting from field and laboratory tests, up to the analysis of the results and the existing correlations between their different index and mechanical properties. , so that data such as the field CBR can be obtained, a parameter that is used for the preliminary design of pavements. This research work was carried out in a series of phases built by different processes, the first phase includes the collection and testing, where 12 samples were extracted in random places of collecting roads, to obtain these samples the PCA technique was used, followed by study and analysis both in the field and in the laboratory. Later in the second phase, the different correlations were elaborated, providing determination coefficients between 50 and 96 percent, the best equation was chosen based on the highest determination coefficient. The results obtained through the correlations serve to carry out preliminary pavement designs, this drives phase three of this work, which was the design of a flexible pavement of a road chosen based on the greatest need of the inhabitants, using one of the correlations made, finally there is phase four where the classification of the soils of the study parishes was carried out based on the AASHTO and SUCS standards, this classification was captured on a map with the help of the ArcGIS software..
